The fertility level of flooded soils will probably change over a period of time. Do not guess at requirements. Take soil samples to determine new fertility levels. Follow recommendations. Allow for nutrients supplied by applied animal manures. When sampling silted fields, make sure the samples represent the soil mix that will exist after deposited silt is mixed with the original topsoil. Soils flooded by surges from ccoastal storms may have salt problems. Check with your Extension agent about soil testing for sodium, salt-tolerant plants, and remedial actions if soil has been flooded with salt water.

Deep tillage and subsoiling can be useful or harmful. Check with your county Extension agent for advice concerning deep tillage and subsoiling.
